Book excerpt: Ce rapport présente la continuation du projet ITheC, qui a été commencé par Pascal Schetelat et Jacqueline Etay. Ce projet étude la viabilité d'une nouvelle technique pour l'obtention des propriétés thermiques des matériaux métalliques (Capacité calorifique et conductivité thermique) avec une mesure indirecte pour des échantillons solides qui présentent un grand nombre de Biot (Bi>0.4). En basant la modulation de la puissance Joule en un pseudo bruit blanc et un système d'identification, on peut trouver la fonction de transfère de la variation de température dans l'échantillon due à la variation de la puissance calorifique. On détermine la capacité calorifique et la conductivité thermique en égalant les fonctions de transfert mesurées en deux points avec le modèle analytique proposé par Fetch [1991] et Wunderlich [2005]. Finalement, avec un algorithme de Gauss-Seidel, on trouve la solution du problème.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Human-Computer Interaction aims to sensitize the systems designer to the problems faced by the user of an interactive system. The book grew out of a course entitled ""The User Interface: Human Factors for Computer-based Systems"" which has been run annually at the University of York since 1981. This course has been attended primarily by systems managers from the computer industry. The book is organized into three parts. Part One focuses on the user as processor of information with studies on visual perception; extracting information from printed and electronically presented text; and human memory. Part Two on the use of behavioral data includes studies on how and when to collect behavioral data; and statistical evaluation of behavioral data. Part Three deals with user interfaces. The chapters in this section cover topics such as work station design, user interface design, and speech communication. It is hoped that this book will be read by systems engineers and managers concerned with the design of interactive systems as well as graduate and undergraduate computer science students. The book is also suitable as a tutorial text for certain courses for students of Psychology and Ergonomics.
